FIELD: physics.
SUBSTANCE: there is pipeline section with two slit-like dielectric openings, microwave generator connected with two transducers of power falling on the flow and transducer of power reflected from the flow, transducer of power passed through the flow, mixer, directed power input device and directed output device that make directed coupler with complete communication, two amplitude detector, microprocessor and indicator. Slit-like dielectric openings make communication hole in power input/output devices and are arranged above pipeline section. Primary line of transducer of power passed through the flow and secondary lines of transducers of power falling on the flow and transducer of power reflected from the flow are connected to ballast loads.
EFFECT: higher sensitivity.
